Sometimes you have no way else to say it. You've thought about it and no matter how you say it, whatever wonderful vocabulary you can design to make sound of your heartfelt emotion for your respective angel, they will never quite grasp it.

For the lucky few, they get to say it and it will be received by a smiling lover but for the most, they can merely stare at the one they love, not say a word, and in their head simply whisper to them through their eyes "I love you so much" only to know it doesn't matter even if they do voice the phrase.

Scenario 1:

Them: "Yeah so I was just eating my dinner and then this *goes on to tell boring but somehow fascinating (what with your feelings and all) story which you ignore as you're too busy falling for their eyes all over again*
You: "Look, listen for a second, I need to tell you something, I love you so much"
Them: "Oh" *Insert own ending here*

Scenario 2:

Them: "Yeah so I was just eating my dinner and then this *goes on to tell boring but somehow fascinating (what with your feelings and all) story which you ignore as you're too busy falling for their eyes all over again*
You: *in your head* "I love you so much"
Them: *Goes on to tell story*
